			BRC numbering is spec'd as: /AutoNumber:Start:Increment:Mode:Separator:Base:Pad:
You can omit start, separator, & pad inbetween the colons, acceptable values below:
Start = 1st-char to begin numbering (0 by default)
Incre = Increment
Mode = P|S|B (Prefix/Suffix/Both)			
Sepa = Text to separate filename from number (spaces must be quoted)
Base = 2-38 (NumberSystem, 10=Decimal, 16=Hex, etc)
............ 37/38 reserved for AlphaCharsOnly (37=Caps, 38=lowercase)
............ 37/38 both require Start=27 for full pad-support
Pad = Min#DigitsUsed (0's prefixed if needed)
An example (without the required /execute):

ExA.jpg -> ExA--001.jpg
ExB.jpg -> ExB--002.jpg
